BOTTOM-POURING LADLE.

SPECIFICATION forming part f Letters Patent N0. 698,565, dated April 29, 1902.

Ie molten metals into molds for casting objects,

especially car-wheels.

`It has been found in casting car-wheels that a better product is obtainedif the molten metal be introduced into the mold in an even stream from the bottom of the ladle, and several bottom-pouring ladles designed for this purpose have been patented. The present invention embraces improvements in the construction and arrangements of parts of such 2e bottom-pouring `ladies whereby the outflow may be easily regulated.

Having thus stated the object and principle of my invention, I will proceed to describe the best mode in which I have contemplated applying that principle and then will particularly point out and distinctly claim the part, improvement, or combination which I claim as my invention.

In the accompanying drawings, illustrating 3o my invention, in the several iigures of which like parts are similarly designated, Figure lis a side elevation, Fig. 2 is a ve rtical section ,and Fig. 3 a top plan view; and Fig. 4 is a crosssection of the guideway and slide, taken sub- 3 5 stantially in the plane of line 4 4 of Fig. 1 and looking down, there being omitted from the drawings all details of means for lifting and transportingthe ladle, which may be of usual or any approved construction.

4o The ladle comprises a steel or other shell et,

open at top, with or without a pouring-lip, and having the bottom b. This shell is provided with a refractory lining c. The bottom has 'a metallic thimble d, surrounding a pouring-opening therein, adjacent to which is an opening in the lining, and this opening is pro- Application iled March 19, 1901.

vided with a specially-prepared bushing e, which is formed with a seat for the plug for regulating the outflow of the contents of the ladle. This plug comprises a cylinder f, of graphite or other highly-refractory material, arranged upon a metal rod g, having its head countersunk Aand protected within the lower end of said cylinder. Above the cylinder f is a cylinder h, of re-brick or other refractory material, also supported upon the rod g,

and this cylinder h is provided with a cap t', fitted to it and to the rod. One side of the ladle is provided with a guidewayj, bolted thereto, in which :is a longitudinally-movable slide lc, having a horizontally-arranged liange Z, to which is adjustably secured a yoke m, as by a bolt 'n and slot o, and this yoke m projects over the mouth of the ladle and receives the upper end of the rod g, which is rigidly secured thereto by a nut p or other suitable fastening. between the cap t' and the under side of the yoke m, around the rod g, and assists in eecting therigid union of the plug and yoke. Any necessary adjustment of the plug is obtainable by means of the bolt it and slot o. The slide lc is provided with lugs r r, between which enters one end of a lever s', which is pivoted upon a stud tof a boss tt on the guide- ,wayj with its handle end projecting beyond the ladle sufficiently to enable a workman to vibrate it to move the slide longitudinally, and thus raise and lower the plug to open and close the opening in the bottom of the ladle to discharge and restrain the outflow of its contents. The guidewayj has its upper end extending above the shell and there provided with an inwardly-inclined projection v, which serves to deflect the molten metal from splashing on the slide and into the guideway when the ladle is being lled,or when in use, or when carelessly handled. Thus a very simple and eliicient bottom-pouring ladle is provided, free from complex operating mechanism, with all parts readily accessible for renewal and repair, and easily operated and cared for.
